Bought the board for $30 five or so years ago at the Kobey Swapmeet in San Diego. It’s a 5’8" twin with thick, down rails and a pin tail. The top of the board has the word “Sweetwater” on it. It has flexible yellow fins and there is a small star sticker on each of the fins. My best guess as to when it was shaped is late '70s early '80s.
The board is really fun in open faced, down the line waves. I would appreciate any information regarding the shaper or the board. Thanks.
